Answer
Hi

Sorry, I live in US but we have the same problem here, the difrence is Audi of America covers all 1.8T engines with oil press. problem (only if all services were done in time).  You will kill your engine soon if you still driving the car.
In USA we check CAM bearings, if any of them (one or more) is bad , Audi replace engine and turbo + all crank hoses.
If all of them are OK , they only replace oil pump+screen and all engine/crancase breather hoses. Also, only sintetic oil have to be used.
I will go to Audi, show the history of all services, you can also say that, they cover it in USA.
Good luck                        pltech
